    Very likely that the intent was just to get the vehicle back near Earth and then use ground based radar for final adjustment.

    The purpose of this alignment telescope was to get the Lunar Module from the moon's surface into orbit near the Command Module.
    I recall a discussion a few years ago about the use of the space sextant on the Apollo 13 mission to reestablish the alignment of the gyros after the power-saving shutdown.  I have a hazy recollection that an accuracy of only about a degree was necessary for that particular function.
